Just received mine today. "Silver" means Chrome, and "Fog Silver" means Silver. I bought mine for my 1/16 Traxxas Rally / Ken Block / Mustang. I wasn't sure if these would fit, but they do, if a bit snug on the 12mm hub. Also, the size is just a hair smaller than the OEM wheels that came with the car. I know next to nothing about RC drift "tires" - these are hard plastic, no rubber. Oh well, should go nicely with my Pro-Line Camaro body.)
